Statutory declarations

Last updated 15 October 2026

You can change your name in Northern Ireland with a statutory declaration, but most people use a deed poll instead.

Both are legal documents that record your former name and your new name. They are made in different ways.

What a statutory declaration is

A statutory declaration is a formal written statement that you sign in front of a solicitor, notary public or Justice of the Peace. They confirm that you made the declaration.

Statutory declarations are used for many legal purposes, not only for changing a name.

Using one to change your name

A statutory declaration that records a change of name is legally valid. HM Passport Office accepts one as evidence of a new name, as well as a deed poll.

Most name changes in Northern Ireland are made by deed poll, so it is the document most organisations are used to. Some organisations may be less familiar with a statutory declaration used for a name change.

How it differs from a deed poll

You must make a statutory declaration in front of a solicitor, notary public or Justice of the Peace. A solicitor will usually charge for this.

You sign a deed poll in front of 2 witnesses who know you, such as friends, neighbours or work colleagues. There is nothing to pay when you sign it.

A deed poll is used only for changing your name.

Apply for a deed poll

It costs £25 to apply for a deed poll with the NI Deed Poll Office. You can pay by debit or credit card.
